You can replace that jack with a RJ-45, if you want a Ethernet Jack, or unhook and start pulling. Most likely once you get it loose at each jack, the cable will pull right out of the wall.
If it's for an alarm system, does it make sense that there are two of these cables that ran parallel for over 80' outside? Also these jacks are only found under two windows out of a total of eight windows?

It depends on who ran the wiring, and why. Most likely previous home owner did it. Now if they used it for Alarm Sensors, that would make sense why they ran them under the windows. Most likely had a 1000' reel of Ethernet Cabling, and instead of purchasing the proper wiring, they just used what they had.

I would be more inclined to think that is the remnants of a LAN. Every cable is a home run to the switch/router.

Not in that setup, and the fact that Jack is not a RJ-11, most likely a RJ31x for a Security system.

Seems odd to have a security system with elements could be simply unplugged. How secure is that?

Why not just tone them out and see where they terminate instead of listening to a bunch of people guess at a picture?

You have to have a RJ31x jck, in order to connect it to the phone line. It has been that way for decades, and has worked fine.

I doubt it is anything connected to an alarm system or it would NOT be in the open. It would be tucked away in a closet, etc. That's where I have been putting them for years and years. More than likely just a two-line phone/phone or phone/fax setup from years past.

Not uncommon to see telephone line installation on outside of building.

Just my humble opinion from experience in the field.

You would be surprised what you see with some of these knock on the door to get you to sign up for their alarm service places do their installs. I have seen some homeowners do the same thing.

Also Telephone & Fax does not use a RJ31x jack.

Good point, to which I answered in the very first post of this thread.

(1) Get rid of it. Pull off these jacks and push the cable into the wall cavity. Patch the small hole on the sheetrock and pretend they are not there. If a tenant wants a land line or DSL service, they can contact the phone company and have them come out and they would most likely run a new line.
(2) Replace the jacks and rewire it to something usable and I am not even sure what this is .
(3) Leave it and when a tenant ask me "what is this for?" I say "it's some kind of a jack"

I wouldn't remove the wire if it is run neatly and out of sight. If you remove it and the tenants call the phone company there is a good chance that they will send out some hack who will drill holes through your exterior siding and run the wires on the outside of the house.
Cut the jacks off and wire up some new phone jacks.
